LED Grow Lights, Pendants, or Strip Lighting? How to Choose Based on What You're Actually Lighting

There's no single best lighting setup—and anyone who tells you otherwise is selling something

I've been managing lighting procurement for the better part of five years now. In that time, I've bought everything from Spider Farmer SE7000 units for our greenhouse operation to chandelier kits for the executive conference room to LED strip lighting for hallway installations across three buildings.

And here's what I've learned: the lighting industry—especially the LED segment—is full of people who want to give you one answer. "Full spectrum is always better." "Grow lights can double as regular lights." "Just buy strips and save money."

None of that's true in practice. What works depends entirely on three things: what you're growing or illuminating, how much control you need over the spectrum, and your tolerance for installation complexity.

So instead of giving you a single recommendation, I'm going to break this down into the three scenarios I've actually encountered—and help you figure out which one you're in.

Scenario A: You're buying for plant growth (greenhouse, indoor farm, or cultivation facility)

What matters most here

This is the scenario where the Spider Farmer name comes up most often in my inbox. And honestly, the questions I get from other procurement people usually boil down to: "Is the SE7000 worth it?" and "Do I actually need the CO2 controller?"

Let me tackle the SE7000 first, because I have firsthand experience with the review situation. When we evaluated the SE7000 in early 2024, I spent maybe two weeks going back and forth. The spec sheet said all the right things—high PPFD output, wide coverage area, Samsung diodes. But the reviews online were all over the place. Some commercial growers swore by it. Others said they had driver failures within a year.

What I eventually realized was this: most negative reviews came from hobbyists running the lights in unventilated spare bedrooms. The units perform differently when you're pushing 80%+ power in a proper commercial setup with climate control. That's not a knock on hobbyists—it's just that the use case matters enormously.

For our 12,000 sq ft greenhouse, we run six SE7000 units at 60-70% power output. After eighteen months, zero driver failures. The PPFD uniformity across the canopy is noticeably better than the older HID fixtures we replaced. But I should mention—we also invested in proper ventilation and monitoring, which I suspect the frustrated reviewers hadn't done.

The CO2 controller question

The Spider Farmer CO2 controller is where I see people either over-spending or under-spending, depending on how they think about it.

Here's the binary struggle I went through personally: the controller costs about $200-250 depending on where you source it. For a small operation, that's not trivial. Do you need automated CO2 monitoring, or can you get by with a basic timer and a cheap CO2 tank regulator?

My gut said "save the money." The data—and I mean the actual CO2 consumption data from our first year—said something different. We were burning through CO2 far faster than we should have been because the manual release system had no timing precision. We were essentially guessing. When we ran the numbers, the payback period on the controller was about seven months just from reduced CO2 waste. That doesn't even account for the yield improvements.

So here's my scenario-A recommendation: if you're running more than 500 sq ft of active cultivation space, the controller pays for itself. Below that, manual management can work—but you need to be honest with yourself about how often you're actually monitoring CO2 levels.

Where I'd push back on the "all-in-one" approach

Spider Farmer sells integrated systems—lights, controllers, everything talking to each other through their GGS platform. That's genuinely convenient. But I've also worked with growers who buy third-party PAR meters, independent CO2 sensors, and separate climate controllers because they want vendor independence.

Honestly? Both approaches are valid. The key is admitting which kind of buyer you are before you spend the money, not after.

Scenario B: You're buying decorative lighting (chandeliers, pendants, accent fixtures)

The category confusion that costs people money

This is where I see the most procurement errors. People search for "chandelier kit" or "light pendant" and end up on pages selling grow lights or industrial lighting because the SEO overlap is real. I've had colleagues forward me product listings asking "is this a good deal for the conference room?"—and I have to point out they're looking at a full-spectrum fixture designed for vegetative growth.

The chandelier kit and pendant world has its own logic entirely. Here, you're not optimizing for PPFD. You're optimizing for:

• Color rendering: CRIs above 90 matter if you're trying to make product displays or workspaces look good
• Form factor: Does it fit the architectural style and ceiling height?
• Installation complexity: Can your facilities team handle it, or do you need an electrician?

We made the classic rookie mistake in 2022: ordered a beautiful commercial-grade chandelier kit for a client-facing space without checking the weight. The fixture was designed for a 12-foot ceiling with structural reinforcement. We had a standard drop ceiling. Cost us about $1,200 in returns and a very awkward conversation with my manager about why the conference room lighting project was delayed three weeks.

What I'd recommend instead

For decorative fixtures, the online reviews are actually useful—but you need to filter aggressively. Look for:

• Photos from buyers with similar ceiling heights to yours
• Comments about what the light looks like in person (not just specs)
• Complaints about installation, because that's where hidden costs live

And if you're buying anything over about 15 pounds, verify the ceiling mount situation before you order. That's been my rule since the 2022 incident.

Scenario C: You're buying LED strip lighting (accent, pathway, or architectural applications)

The cutting question

"Where can you cut an LED strip?"—I've answered this question from colleagues at least a dozen times now, and I've come to realize that the search intent is usually deeper than it looks. People aren't just asking about physical cut points. They're asking: "Can I customize this to fit my actual installation without buying too much or too little?"

The short answer: most LED strips have designated cut marks every 2-4 inches (usually marked with a scissor icon). You can cut there. You cannot cut just anywhere, or you'll sever a circuit and kill that segment permanently.

My gut told me to buy 20% extra on our first strip installation. That was the right call—not because we destroyed segments while cutting (we didn't), but because we had misjudged the corner runs and needed the extra length. The "buy exactly what you need" advice you see online assumes you have perfect measurements. Nobody has perfect measurements on their first strip install.

Where strip lighting doesn't work

Strip lighting is excellent for accent and ambient applications. It's terrible for task lighting. If you're trying to illuminate a work surface or reading area, you need a different solution. I've seen procurement requests asking for strip lights to replace office ceiling lights—that's a mismatch that will disappoint everyone involved.

Also worth noting: strip lighting quality varies enormously at different price points. The cheap strips from generic suppliers tend to have adhesive failure within 12-18 months. You're not saving money if you're re-installing them twice.

How to decide which scenario you're in

Here's the simplest framework I can give you:

• If the primary goal is plant growth or cultivation: Scenario A. Look at PPFD, spectrum control, and whether you need CO2 integration. Budget for $0.80-$1.20 per watt if you're going with reputable brands.
• If the primary goal is aesthetics and architectural appeal: Scenario B. Verify ceiling compatibility, check CRI ratings, and ask your facilities team about installation capacity before ordering.
• If the primary goal is accent or ambient lighting over a large area: Scenario C. Confirm cut points, buy 15-20% extra, and don't expect task-light performance.

And if you're buying for multiple scenarios—which many companies are—use a separate vendor for the grow lights and the decorative fixtures. The crossover expertise doesn't exist in one place, and pretending it does will lead you to spend money on things that don't fit either use case.

I made the binary mistake early in my career of trying to find one supplier who could "do it all." The vendor who eventually earned my trust was the one who said, "This isn't our strength—here's who does it better." That's worth more than any spec sheet.
